JAMES WRIGHT, OF JACKSON, TENNESSEE, ASSIGNOR TO THE NEW ERA COTTONMANUFACTURING COMPANY.

SPECIFICATION formingpart of Letters Patent No. 233,313, dated October12, 1880.

Application filed May 3, 1880. (No model.)

To all whom it may concern:

Be it known that I, JAMES WRIGHT, a citizen of the United States,residing at Jackson, in the county of Madison and State of Tennessee,have invented certain new and useful Improvements in Oarding Attachmentsfor (lotton-Gins; and I do hereby declare the following to be a full andexact description of the same, which will enable others skilled in theart to which the invention appertains to make and use the same,reference being bad to theaccompanyin g drawings, and to letters andfigures of reference marked thereon, forming part of this specification.

This invention relates to improvements in carding attachments forcotton-gins; and it consists in a novel construction and arrangement ofmechanism for separating the seeds from the fibrous portions of thecotton and feeding the latter to the carding-cylinder, all as I will nowproceed to describe.

In the drawings, Figure 1 represents a side elevation of a machineconstructed in accordance with my invention; Fig. 2, a sectional view ofthe same, and Fig. 3 a front view.

Similar letters of reference in the several figures indicate the sameparts.

A represents the frame of the machine, having boxes or bearings E, forthe reception and support of the shaft]? of an ordinary cardingcylinder,G. The carding-cylinder is provided with card-teeth H, inserted in abacking, I, of leather or other like material, in the usual manner.

At one end of the frame, andin front of the carding-cylinder, arelocated vertical standards or guides O O, in which are journaled fourrolls, D D and D D, the two former being at the top and bottom,respectively, and the two latter arranged between them. One of thejournals of the lower roll, D is extended out beyond the ends of theother rolls, and carries a gear wheel, L, which meshes with anothergear-wheel, L, driven by a pinion, Q, on the shaft of thecarding-cylinder. The opposite end of the lower roll, D is provided witha pinion, M, which meshes with a pinion, N, on the lower roll, D, andthe latter pinion, in turn, meshes with a pinion, O, on the upper roll,D. The top roll, D, is not geared at either end, but simply rests uponthe upper roll D, and revolves therewith by frietional contact, andoperates as a press-roll. Springs or weights are preferably applied toits journals to increase the pressure on the drawing-rolls D D below.

P indicates an inclined plate arranged in front of the tier of rolls,and extending from side to side of the frame. It is provided at itslower edge with a series of spring arms or fingers, 10, which are curvedinward slightly and terminate a little above the point of contact of thetwo rolls D D.

The operation of the machine is as follows The cotton being fed into thehopper formed by the inclined plate P and the tier of rolls, its fibrousor flocculent portions are seized by the rollers D D, separated from theseeds, and carried through to the carding-cylinder, leaving the seeds tofall out between the yielding spring fingers p, and preferably into areceptacle placed in front of the machineto receive them.

For the purpose of enabling the rolls to better seize hold ofthe fibrousportions of the cotton, they are preferably covered with leather,rubber, or other similar elastic material, in a manner well known in theart.

This invention is designed for use in connection with the gin-feedingmachine for which Letters Patent N 0. 172,680 were issued to myself andJ. O. Smith, Jr., January 25,1876, and also in connection with theattachment for carding-engines for which Letters Patent No. 179,834 wereissued to myself and the said Smith, July 11, 1876.

Having thus described myinvention, Iclaim as new- The combination, withthe carding-cylinder and the tier of rolls D D D D of the inclined plateP, forming the front side of the feed-hopper, and having a series ofcurved springy separating-fingers, which operate to guide the cottonbetween the drawing-rolls D D, and also permit the escape of the seeds,substantially as described.
